Manipulation of photonic and phononic coupling in the coupled cavities plays a crucial role in the development of nonreciprocal devices and photon-phonon conversion. Here, we theoretically investigate how the phase gradient of a driving laser affects the coupling between photonic and phononic modes. This, in turn, affects and offers the controllability of the nonadiabatic dynamics of the population of hybrid eigenmodes following a sudden change in the optomechanical coupling. We show that the controllable nonadiabatic dynamics can be attributed to the phase-induced alteration of the bandgaps in the hybrid eigenmodes. We further demonstrate that the phase-assisted control of the relative weight of photonic and phononic modes in the hybrid eigenmodes also contributes to the nonadiabatic dynamics. Finally, we investigate the effects of phase on the coherent conversion of photon-phonon in a finite-size array.
